Aspectos morfológicos do fígado do cervo-do-pantanal (Blastocerus dichotomus)

A descrição macroscópica do fígado do Cervo do Pantanal foi realizada com ênfase à forma, localização, meios de fixação, disposição e lobação. Foram utilizados os órgãos de animais provenientes do Projeto Cervo do Pantanal de Porto Primavera, que morreram no período de quarentena, mediante inspeção visual e posterior dissecação. Foi constatado que o fígado do Cervo do Pantanal localiza-se na porção cranial da cavidade abdominal, à direita do plano mediano, possui coloração castanho-avermelhado e apresenta duas faces, quatro bordas, quatro lobos e cinco ligamentos. A principal característica que o difere dos fígados dos outros ruminantes é a ausência de vesícula biliar.

Padrões de distribuição de líquidos obtidos com bicos TF-VS4, TJ60-11006 e TQ15006 em mesa de prova

The performance of a spray boom can be evaluated from its individual nozzle distribution patterns determined in a patternator (test table), as discussed by Perecin et al. (1994). The distribution pattern of three nozzle types obtained in a patternator at six heights were compared in order to propose a formula for determining the variation coefficient. The simulation of a spray boom was conducted from individual nozzle distribution patterns, and obtained the random variation coefficients (RVC) and the systematic variation coefficients (SVC). The results showed good performance of the TF-SV4 nozzles, with CV smaller than 10%, for nozzle spacing as large as 50 cm. The TQ15006 nozzles showed high variability in the central region of the distribution pattern, resulting in high CV from nozzle spacings as narrow as 25 cm. The TJ60-11006 behaved as intermediate between TF-VS4 and TQ15006. The formula proposed for determining the variation coefficient is [(RVC) 2+(SVC) 2] 1/2.

Classificação automática de padrões projetados por um sistema de luz estruturada

One of the main problems in Computer Vision and Close Range Digital Photogrammetry is 3D reconstruction. 3D reconstruction with structured light is one of the existing techniques and which still has several problems, one of them the identification or classification of the projected targets. Approaching this problem is the goal of this paper. An area based method called template matching was used for target classification. This method performs detection of area similarity by correlation, which measures the similarity between the reference and search windows, using a suitable correlation function. In this paper the modified cross covariance function was used, which presented the best results. A strategy was developed for adaptative resampling of the patterns, which solved the problem of deformation of the targets due to object surface inclination. Experiments with simulated and real data were performed in order to assess the efficiency of the proposed methodology for target detection. The results showed that the proposed classification strategy works properly, identifying 98% of targets in plane surfaces and 93% in oblique surfaces.

Composição química e aspectos morfológicos de mudas de Tabebuia chrysotricha (Standl.) produzidas em diferentes substratos e soluções de fertirrigação

The work aimed to study the formation of Tabebuia chrysotricha Standi, seedlings in function of four substrates, varying the covering fertilization solutions. To compose the substrate it was used fibrous and granulated coconut fiber obtaining the following treatments: 100% fibrous (100% F), 60% fibrous + 40% granulated (60% F+40% G), 40% fibrous + 60% granulated (40% F+60% G) and 100% granulated (100% G). The basis fertilization was the same for all treatments and the solutions of covering fertilization varied in order to obtain complete solutions with electric conductivities of 1.06 dS m-1, 2.12 dS m-1, 3.2 dS m-1 and 4.25 dS m-1. The propagative material was sowed directly in plastic containers (120mL) with the respective substrates. The fertilization was received through sub-irrigation once a week, respecting the treatments of fertilizations. Seedlings produced in 100%G had been taller and higher than the others. The chemical analyses of aerial part were obtained when the seedlings were ready for expedition (height of 20 cm). The seedlings production in substrate 100% F and 60% F+40% G allowed them to have higher N, S, B, Mn and Zn concentrations in the aerial part. The production of T. chrysotricha seedlings is recommended in granulated coconut fiber substrate and fertilizer solutions with EC of 1.06 dS m-1.

Caracterização de biotérios, legislação e padrões de biossegurança

The use of laboratory animals in conjunction with research on the human organism provides a basis for on understanding of several important physiological and pathological processes. Besides, the results of experimental studies enable technical and safety improvements to be made in surgical techniques used in the medical clinic. As living biological material is involved, we should guarantee its physical well-being, taking into account microbiological contamination and the genetics, nutrition and correct manipulation of the animals, in order to avoid incorrect conclusions from the experiments or unnecessarily large numbers of animals being used. In parallel with the concerns and legislation on the use of laboratory animals, there is also a growing preoccupation with the welfare and safety of those who handle the laboratory animals, since they run the risk of acquiring occupational diseases through contact with zoonotic pathogens or developing allergies. Prevention requires the application of modern technological advances in the design of the animal house and in the work routines. Unfortunately, few establishments in Brazil possess staff with adequate training and a basic infrastructure of research that includes the laboratory animal breeding centers, equivalent to those existing ones in the United States and Europe.

Geração de padrões de corte n-grupos para a indústria moveleira

Neste artigo são apresentadas propostas de soluções para o problema de geração de padrões de corte n-grupos para o corte da matéria-prima na indústria moveleira. Este problema NP-difícil aparece em diversos outros processos industriais que incluem o corte de painéis retangulares grandes de tamanho padrão em retângulos menores. O planejamento dos cortes é um aspecto importante do planejamento da produção nestas indústrias, pois efeitos negativos tais como o perda de matériaprima e tempo de preparo da máquina de corte podem ser minimizados, diminuindo assim os custos de produção. É estudada a eficiência de modelos lineares inteiros para resolver o problema do corte guilhotinado bidimensional propostos em [33,34], bem como o seu uso na geração de colunas para o problema de corte de estoque. São usados dados reais de uma fábrica de móveis de pequeno porte característica do pólo moveleiro de Votuporanga/SP. Os resultados obtidos indicam que as estratégias propostas geram perdas dentro dos requisitos exigidos pela fábrica. © SPM.
